One thing that happens when you do genealogy is that you will meet people who are related to you in a distant way. It is inevitable. I became friendly with someone who is probably a 5th cousin or so. In our many interactions, she told me that she had come across a marriage for one of my ancestors that I had never seen. It was in another town.
To put it as simply as possible, I had Ann Deacon as my ancestress and she said it was really Ann Spinks. My ancestor John Ollard, had two wives named Ann. He married Ann Deacon in Newton, had children there and then Ann Ollard died in 1737. I can be forgiven for thinking she was Ann Deacon.
I contacted the Wisbech Fenlands Museum online and asked them to check the records for Tydd St Giles for a marriage between John Ollard and Ann Spinks. Yes, there is one, in 1716 the year before my ancestor Spinks Ollard was born. So it seems, he was given his mother's last name as his first name. There is no death recorded in either town for Ann Deacon Ollard but no doubt she died before 1716.
So another mystery is solved and now my genealogy is correct. Thank you, Heather.
